Fifteen more than half a number is 9
rusak2 [61]

For this case, the first thing we must do is define a variable.

We have then:

x: unknown number

We now write the equation that models the problem:

(\frac{1}{2}) x + 15 = 9

From here, we clear the value of x.

We multiply both sides of the equation by 2:

(\frac{2}{2}) x + 2 (15) = 2 (9)\\x + 30 = 18

We subtract 30 on both sides of the equation:

x + 30 - 30 = 18 - 30\\x = -12

Answer:

The value of the unknown number is given by:

x = -12

Dennis_Churaev [7]

Answer:

$36

Step-by-step explanation:

Jim worked from 8am - 2 pm , which is 6 hours

Woody worked form 10am - 2pm, which is 4 hours

If we take the total time (4+6 = 10) and divide the amount they got, we have:

$60/10 = $6 per hour worked

Since Jim worked 6 hours, he will be paid 6 * 6 = $36

The rest, 60 - 36 = $24 would be paid to Woody (he worked less).

Jim's fair share of earning is $36
